; IMBRQVED RAILWAY-GATE.

Thechedule referred to in these Letters Patent and making part; of thesame.

To all whom it may concern;`

Bc it known that I, `Pn'rnn CAMPBELL, of Carroll# town, in the county of`Gambria, and State of Pennsylvania, have invented a new and usefulImprovement .in RailroadGates; and I do hereby declare thefol- "lowingtobe a full, clear, and exact description thereof,

sufficient to enable others skilled in `the art to which my inventionappertains, to make and use the saine, reference being had to theaccompanying drawing, ibrming part of this invention, "andin whichiFigure 1 is a top view; Figure 2, a partial front view;` and Figure 3,an end view, from the line y y, fig. 1.

The gate which `forni's `the subject of this invention, is held inposition across the `track by means of levercatches, pivoted tothe railsin such a manner that the weightof an approaching caror train depressesthe rails and releases the` catches, allowing the gate to be thrown backagainst its post when struck bythe car or engine, and thereheld by aspring until the train has entirely passed, `'when the rails resumetheir former position, thereby releasing the` spring which holds thegate open, and permitting it to swing across the track, whereit is heldas' before. l i s l'lhe invention consists in the construction and arrangement of parts as hereinafter set forth.

[will now proceed to describe my invention in detail referring to thedrawings, in the several figures of wlnclrsimilar letters indicate likeparts. y

The gate proper is constructedin any suitable manuel" which will insurestrength, and is hung to a post, A, by hinges, soconstructed or arrangedIas to canse the gate t`o close by gravity.

Blnnay represent the rails of the track.

The inner rail,B, is rigidly secured to the ,sleepers CC C C?, but theouter one, B', is fastened only at C and G3, the other sleepers beingcut away to allow of the depression'ofthe rail.

D is a sort of platform at the side of the track, on which are pivotedbarsE E', having bevelled endsand with shoulders a a, between which thegate is held in position across the track.`

l F F are levers, each ofv which is pivoted at one'end ,to the rail B',and at `the other to one of the bars l These levers' each have afulcrum, 1).

i Gr l' are rods, with bent portions l c c, which have more orlcsselasticity. i

These rods are pivoted at d d, and are connected with the outer rail B'.Their oiice is to hold the gate 'opernfas will ce hereinafter described.

H Hare posts, againstwhich the gate is thrown when struck by the car` orengine. 4 'y They are each provided with a spring,re, with which frombeing loosened or injured.

AI I represent springs, applied to the gate for receiving andneutralizing the shock when the gate is opened by the car or engine. l

The gatel opens in either direction. v l

'lhc operation is as follows:

Suppose a train to be approaching in the direction of the arrow, figs.,1vand 2. As soon as the. engine rea-ches the section of track shown inthc drawing, the rail B\\vill be depressed, at'the same time depressingthe bar E, through the medium of lever F. The engine then strikes thegate, or rather the springs at-y tached to it, and throws it backagainst the post H', where it is held by the bent portion of rod Gspringing upand preventing its return. As soon as -the -train haspasseth'the rail B', being relieved lof pressure, springs up, depressingthe holder G', which releases the gate, and elevating the catch E. Thegate now swings` by gravity to the position in which it is shown, whereit is held between the shoulders a a. of `'the bars E .E2

v.lfhe advantages of this gate are, that itis very sirnple andinexpensive, and is at the same time antomatic and certain in itsoperation.

Having thus `described my invention,

What L claim as new, and desire to secure by Let'- ters Patent, isc l.The self-closing gate, provided with springs I, as and for thepurposeset fortln l 2. The pivoted spring-holders G G', when connected with therail B', for the purpose and substantially as described.
